Claude Style Patch: pricing, features, alternatives

Claude Style Patch is a drop-in style section for CLAUDE.md that changes how Claude writes prose. The repo andrewroxby/claude-style-patch is CC0, created 2026-09-08. On 2026-09-08 GitHub listed 65 stars and 3 forks. r/ClaudeAI posted it as a workflow against "word vomit" replies. This is a STYLE.md snippet you append, not a SKILL.md pack and not a YouMind marketplace Skill.

Compare Marketing Skills if you wanted a 50-skill marketing library, Humanizer if you wanted anti-AI-detect rewriting, or Claude Skills if you still needed how skills load.

Key Features

Drop-in install: curl -sL https://raw.githubusercontent.com/andrewroxby/claude-style-patch/main/STYLE.md >> ~/.claude/CLAUDE.md. Same file also pastes into a Claude Project custom instruction or any system prompt.
Bans with repairs: README says Claude follows a concrete rule better than a preference. Each habit is named, shown, and rewritten. Targets include announcing a point before making it, colon-hinged sentences, verbless fragment openers, and stacked compressed phrases.
Scope beyond chat: README covers generated documents, deliverables, and code comments, not only replies.
About 1,600 words: author says the context cost is worth it in Claude Code and claude.ai.
Battle-tested claim: author drove it on Opus 4.8 and Fable turns. That is first-party testimony, not our eval.

Limitation: compliance is not total and degrades on long threads. README says Fable follows the spec better than Opus on long threads. The opening paragraph tells Claude to re-check the rules when material turns dense. That helps and does not fully solve it. 65 stars on day one is a heat signal, not an audit.

Use Cases

Claude Code users tired of 124-word answers to "which button next".
claude.ai Project owners who can paste STYLE.md into custom instructions.
People writing docs with Claude who need the same bans on deliverables, not only chat.

Getting Started

Open github.com/andrewroxby/claude-style-patch.
Append STYLE.md to ~/.claude/CLAUDE.md, or to one project's CLAUDE.md.
On a long thread, tell Claude to hew closely to the response style instructions before a long prompt or a new document.
Confirm Humanizer if the job is stripping AI-detect fingerprints, not house voice.

First-party resource: STYLE.md.

Frequently Asked Questions

Is this a SKILL.md pack?

No. It is a CLAUDE.md section. There is no npx skills add installer.

Does it work outside Claude Code?

Yes. README says paste it into a Claude Project or any system prompt.

Will it stay on after 50 turns?

README says it degrades on long threads. Re-invoke the style instructions.

Alternatives

Humanizer: rewrite for human texture, different job.
Marketing Skills: 50 marketing skills, not a prose ban list.
Writing Skills: broader writing pack if it is in your catalog path.

Tips

Keep the file. Do not summarize STYLE.md into three adjectives.
On Fable vs Opus, README prefers Fable for spec following.
If you only needed shorter answers, a one-line "be concise" still fails. That is why this patch exists.

Conclusion

Claude Style Patch is a CC0 CLAUDE.md drop-in for people who already pay for Claude and hate Claudish. Start at the GitHub repo, append STYLE.md, then decide whether a full skill pack was what you wanted.
